  1. Soil pollution

  2. SOIL POLLUTION Contamination of soil by human and natural activities which cause harmful effects on living beings

  3. Sources of soil pollution Industrial wastes Urban wastes Agricultural wastes Radioactive pollutants Biological agents

  4. Industrial wastes Paper mills Chemical industries Tanneries Textiles Oil refineries Fertilizers Pesticides Coal & mineral mining industries & so on

  5. Effects Alters the biological properties of soil Disturbs human food chain Serious effects on human life

  6. Urban wastes Sources • Plastics • Glasses • Garbage and rubbish materials • Rubber • Street sweepings • Fuel residues • Discarded manufactured products Effects • Nondegradables harm the environment

  7. Agricultural practices • Sources • Modern agricultural methods • Use of fertilizers • Pesticides • Herbicide • Weedicides • Farm waste • Debris • Eroded soil containing inorganic chemicals

  8. Radioactive pollution • Sources • Explosions of nuclear dusts • Radioactive wastes • Effects • accumulates thereby creates soil pollution

  9. Typical examples of radioactive pollution • Radio nuclides of Th, U, K,C • Explosion of nuclear weapons • Nuclear reactor wastes like Ru, I, Ba,La Cs etc., Effects • Rain water carries the harmful wastes into the soil • Nuclear wastes emits gamma radiations

  10. Biological Agents • Source • Human excreta • Animal excreta • Bird’s excreta

  11. CHARACTERISTICS OF UNTREATED WASTES OF CHEMICAL INDUSTRIES

  12. CONTROL OF SOIL POLLUTION

  13. CONTROL OF SOIL EROSION • TREE PLANTING • VARYING CROPPING METHODS • SUBSTITUTING ANIMAL MANURES INSTEAD OF CHEMICAL MANURE

  14. 2. CONTROL OF UNWANTEDMATERIALS • PROPER DUMPING OF UNWANTED WASTES • CONSTRUCTIONS CAN BE CARRIED OVER DUMPED FIELD

  15. OTHER METHODS TO CONTROL SOIL POLLUTION • PRODUCTION OF NATURAL FERTILIZERS • PROPER HYGIENIC CONDITION • PUBLIC AWARENESS • RECYCLING & REUSE OF WASTES • BAN ON TOXIC CHEMICALS
